Geranium plant named ‘FN Chocolate’

ABSTRACT

A new and distinct cultivar of Geranium plant named ‘FN Chocolate’, characterized by its upright, outwardly spreading and mounded growth habit; freely branching habit; dense and full plant habit; freely flowering habit; dark purple-colored flowers; and no requirement for vernalization.

Botanical classification/cultivar designation: Pelargonium×domesticum cultivar FN Chocolate.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, commercially known as Regal Geranium, botanically known as Pelargonium×domesticum, and hereinafter referred to by the name ‘FN Chocolate’.

The new Regal Geranium is a product of a planned breeding program conducted by the Inventor in Foxley, Norfolk, United Kingdom. The objective of the breeding program is to develop new Regal Geranium cultivars with compact growth habit, numerous flowers, and interesting flower and foliage colors that do not require vernalization for flowering.

The new Regal Geranium originated from a self-pollination made by the Inventor in May, 1997 of a proprietary Pelargonium×domesticum selection identified as RPOAU, not patented. The cultivar FN Chocolate was discovered and selected by the Inventor as a flowering plant within the progeny from this self-pollination in a controlled environment in Foxley, Norfolk, United Kingdom.

Asexual reproduction of the new cultivar by terminal cuttings taken at Foxley, Norfolk, United Kingdom, since January, 1998 has shown that the unique features of this new Regal Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘FN Chocolate’. These characteristics in combination distinguish ‘FN Chocolate’ as a new and distinct Regal Geranium cultivar:

1. Upright, outwardly spreading and mounded growth habit.

2. Freely branching habit; dense and full plant habit.

3. Freely flowering habit.

4. Dark purple-colored flowers.

5. No requirement for vernalization.

Plants of the new Regal Geranium differ primarily from plants of the parent selection in the following characteristics:

1. Plants of the new Regal Geranium are more compact than plants of the selection RPOAU.

2. Plants of the new Regal Geranium flower earlier than plants of the selection RPOAU.

The new Regal Geranium can be compared to the cultivar, Burghi, not patented. However, in side-by-side comparisons conducted in Foxley, Norfolk, United Kingdom, plants of the new Regal Geranium differed from plants of the cultivar Burghi in the following characteristics:

1. Plants of the new Regal Geranium were more freely branching than plants of the cultivar Burghi.

2. Plants of the new Regal Geranium had smaller flowers than plants of the cultivar Burghi.

3. Plants of the new Regal Geranium and the cultivar Burghi differed in flower coloration.

4. Plants of the new Regal Geranium did not require vernalization for flowering whereas plants of the cultivar Burghi required vernalization for flowering.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Flower and foliage colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Regal Geranium.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘FN Chocolate’.

The photograph at the bottom of the sheet comprises a close-up view of a typical open flower, a typical flowering umbel, a typical flower bud, the lower surface of a typical developing leaf, and the upper surface of a typical mature leaf.

DETAILED BOTANICAL DESCRIPTION

The cultivar FN Chocolate has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice in a polycarbonate-covered greenhouse during the winter and spring with day temperatures ranging from 55 to 75° F., night temperatures ranging from 50 to 65° F. and light levels ranging from 4,000 to 8,000 foot-candles. Plants used for the photographs and description were about 22 weeks from planting rooted cuttings and were grown in gallon containers. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
